Fourier Filtering

Dear Remnant, this is not a proposal for next patch :D.

Currently I am fighting an uphill battle on Renderosity Vue forum in order to show people how to create sharp terrain renders using Vue standard terrains (Vue procedural terrains are much slower than standard ones so the speed advantage matters).

The core of the solution is to counterract Vue atrocious smoothing of the highest frequencies in the heightfield bitmap.

Currently, a modification of the sharpening macro does quite well but I found wondering… what if Remnant added Fourier filtering to WM? In this case it would be possiible to perform very precisely band limited frequency highpass which would obviously be better than the ad-hoc unsharp masking approximation.

What if?

Bye!!!

Or someone could use the PDK to create it :slight_smile:
Anyone?
